That size of barrel is fairly cheap as listed. It would have to be on a trailer to be mobil, hard to cater with a stationary cook station. To be honest I would think for a company that does lots of catering would be best served with a smaller smoker with more cook stations on the trailer. That barrel could be a smoker one end and possibly modified for argentinian grill on one end. But as with everything you stated before the amount of hours in that build would make the cost to the point of choke for them. Untile they see a solid market to justify the cost they would not likely change their current ways.
